arc ultra

I just upgraded to the arc ultra but I’ve found that when playing Dolby atmos music the dialogue is very low even when I use the enhancement. I didn’t seem to have this issue with the previous arc. I’m using passtrough from my e arc and I’ve checked everything to try and figure it out.

I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, Sonos’ lawyers get sensitive about GDPR, I suspect.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
